At the end of June the necessary amount of grain was accumulated by the arrival of a large caravan from Mooltan. The army was now to cut itself entirely free from its former lines of supplies, and would have to depend solely, upon the country for food, as the ever-increasing boldness of the Beloochees in the Bolan Pass, and of the Afghan marauders between Quettah and Candahar, had made it impossible for convoys, unless very strongly guarded, to make their way up.

The advance began at two o'clock on the morning of the 28th, and four hours later, after passing through a fertile district, the troops encamped at the village of Killa Azim. Here they obtained barley for their animals, and peasants from other villages brought in an abundance of chopped straw for the camels. At midnight the trumpet sounded, and an hour later the army moved forward again as far as Kheil. Four days' further march brought them to Kelat-i-Ghilzye, the chief town of the Ghilzye tribes. Two or three hundred of their horsemen galloped away as the troops approached.

Marching ten miles a day, the army followed the valley of the Turnak, which afforded an ample supply of water for all their needs. The country was mountainous and desolate, the dreariness being only broken by small villages with their orchards and patches of cultivated ground. Grain was brought in in abundance. The force was now far above the plain, the heat ceased to be oppressive even in the middle of the day, and the mornings and evenings were delightfully cool. Nevertheless, the number of sick increased, owing to the bad quality of the flour and the absence of vegetables. The country now became more thickly populated, little villages, with the fortified dwellings of their chiefs, being thickly scattered about. The hostile tribesmen followed the march on both flanks, and many skirmishes took place; on one occasion the Ghilzye marauders made an attack on the line of march, but were driven off with heavy loss. On the 17th a nephew of the Ameer rode in with fifteen followers. He had gone to Ghuznee with his brother to aid in its defence, but suspicions being entertained by Mohummed Hyder, the governor, of their fidelity, his brother was seized and put to death, and he himself only escaped a similar fate by flight.

As they approached Ghuznee, Sir Alexander Burnes said to Angus: "Mr. Campbell, I shall be glad if you will resume your Afghan costume and ride to-morrow at daybreak with a party of six of Hajee Khan Kakur's men, and ascertain whether the enemy are in strength outside the fortress and intend to oppose our approach. If they do, we shall leave the baggage here under a strong guard and proceed to attack them. If they retire into the fortress, we shall advance as we have been doing, for possibly the siege may last some time, and it would be as well to take our ammunition and stores with us. Will you undertake that mission? I do not wish you, of course, to approach the enemy very closely. They will naturally take you for a party coming to join them, and will pay no attention to you. Half a mile will be near enough for you to go to the fortress. The disguise is only necessary because they too may have parties out, and should any come suddenly upon you, you would pass without suspicion or question; and indeed should you be stopped, your knowledge of the language is quite good enough to pass in any case. I have requested Hajee Khan to choose well-mounted men. We shall remain here to-morrow, and the general will send out a troop of cavalry to meet you on your return half-way between this and Ghuznee, so that should you be pursued, you will know that you will meet with succour before going many miles. The fortress itself is some twelve miles from this camp."

"I will undertake it willingly, Sir Alexander."

Accordingly on the following morning Angus set out. Azim asked leave to accompany him, but he refused.

"Your horse is not a very fast one," he said. "It is a good beast, but we may have to ride for our lives, and you would soon be left behind. It is not a dangerous expedition, but in a country like this there is always the possibility of a surprise."

After riding for two miles the fortress of Ghuznee was seen. It was situated on a high rock and surrounded by a wall of great height and strength, and was regarded by the Afghans as absolutely impregnable. As they approached, and could make out the strength of the fortifications, it seemed to Angus that, except by famine, it would be next to impossible to capture it. The general had left the few heavy cannon he had brought with him at Candahar because of the extreme difficulty of getting transport, and the light field-pieces could make but small impression indeed on these massive walls. When he approached within a mile he halted. There were no signs of any Afghan force in front of it. It was, of course, possible that they might sally out when they saw the army approaching, but at present there was nothing to show that they meant to do so. He was about to turn, when he was suddenly seized from behind, and in a moment his hands were bound tightly to his side by the sashes of two of his escort. The Afghans burst into a shout of triumph.

"Infidel dog," one said, "did you think because Hajee Khan Kakur is a traitor that all his men are also. You came to see Ghuznee. You shall see the inside as well as the outside."
